All right. I changed the standpipe and dummy plug along with injectors 1 & 5. Started tonight around 6:45 and finished up around 9. All my issues mentioned earlier seem to have been resolved. The standpipe & dummy plug o-rings were not torn or damaged in any visible way. A thought struck me while I was working. Is it possible for the injector to be damaged in such a way as to allow the high pressure oil system to lose pressure or bypass under WOT in such a way as to trigger a 2290 code?Yes it can if the injector oring in the top of the injector goes bad it can Leak HPO there at the HPO Rail & Inject joint

Do you mean where the oil rail sits into the injector?

My engine has an 04 build date and has the stc fitting. Apparently there was a cross over period in 04.

Mike - I believe that ALL 2005 model year engines had the STC fitting, even if they had a 2004 build date. It is the 2004 model year and earlier trucks that did not have it (if that makes sense). Sometime around the 3rd quarter, the auto manufacturers start building the next years models.

Excursions were different as far as what motor they had in them in what year. Maybe Moe or Mike can tell us what the date was exactly or someone in the Ex. forum.

Thanks for the comments and bits of info. It would appear that the P2290 code was either from the standpipe, dummy plug or the HPOP oil rail/injector seal. Ive driven about 150 miles since and the code is gone.
I have one code remaining (P0649) that is unrelated to this problem so will start a new thread for it.

I spoke too quick....P2290 is back. It took some serious application of throttle to do it but it did return. Normal driving it does not show up. Just to recap, Stand pipes and dummy plugs are updated in both sides, it would appear that I do not have the notorious STC fitting. ICP sensor and HPOP are all thats left...

Ok, now I've got real problems. I'm stranded along the road with P0232 (P0232 Fuel Pump Relay dvr circ fail off) as well as P2290. I tested the connector and have 1.8 volts to the pump and there is no fuel at all at the test port. Filters have about 2500 miles on them. Tank is full. I only got about 6 miles from fuel station when it started chugging and missing. Now no start. Any ideas?

P0232 C O R Fuel Pump Secondary Circuit High Voltage present at the Fuel Pump monitor circuit when it has
NOT been commanded "on" for more than 1 second.
Indicates short to power,sticking relay.
Looks Like bad connection or relay or shorted wire 1.8V isnt enough
Dont even try to start till you get fuel at upper filter

I unplugged the pump and put 18 volts to the pump and got it pumping. Then I attempted to start the truck and it started right up and idled smooth but the code came back in about 30 seconds so I'm thinking that the pump may be shot. I'm not going anywhere with this thing til I try a new pump. I've got a new fuel pressure gauge but haven't gotten the time to put it in yet. It may have warned me about this before it turned into something so drastic.
